Introduction

The Vox Ranger EQ Module is a graphic equalizer for the vocal range with passive coil filters in eight bands. It employs bell filters, each with individually optimized bandwidths, boost and cut values.

The concept of the Ranger EQs for the RackPack modular system is characterized by two decisive features that separate them from tradi- tional designs. First there is the basic idea of specialized modules for typical instrument or vocal ranges. This follows a consistently musi- cal approach, but also the design of each filter is based upon musical demands alone—center frequency selection is not governed by techni- cal ISO rules, but relies on our own experiences and the preferences of well-known colleagues.

In contrast to statical graphic EQs with always the same center fre- quencies in repeating octave distances, the Ranger EQ modules are much better suited to work with specific instruments and their pecu- liarities—and only different frequency ranges do allow to effectively separate instruments in a mix.

The second characterizing feature follows the idea of a modular design and affects both the filter technology and the user interface. Why did we chose a graphic EQ design? For a fully parametric EQ with all neces- sary controls there would be space for one band on the module front. Our graphic EQ offers eight bands—a bandwidth control is less impor- tant, and different EQ modules can be combined to configure a large and, if needed, complex EQ system.

But a traditional graphic EQ with an active filter design did not seem to match our idea of a holistically musical approach. We decided for a rare technical solution: the combination of passive filters with a graphical user interface. Based upon individually specified, custom-made coils, these filter designs convince with outstanding musical qualities.

Finally, the general advantage of modular systems becomes clearly obvious when planning individual systems: A vocal recording channel with RackPack modules can be configured in very specific ways, while a complex EQ system may have a completely different focus.
